Hi, can someone please show me how to most elegently do this?.....
I have a textbox, and I want to search the contents of it and replace
all instances of a certain word, and replace that word with something
else. For the purposes of this it could be replacing "green" with
"blue". Can someone please show me how to properly do this? :)
Sincerest regards, Alxasa.

OK.
or

Nonsense.

Good of you to wash some ears, Mick, but eval() is evil.

That was premature. The constructor is RegExp().

If you do not consider it nonsense, then you have to deal with this
question:
What does this accomplish more that cannot be done better with calling the
constructor function?

constructor function?
It handles control characters, "\n", "\t" etc..., a little better.

What do you suggest to do if I want to do a search in TextBox ? I know that
using RichTextBox, we could have Find method to search for a specific word
or information but I was wonder if somebody knows some methods for Find and

Thanks

Hi,
I need to replace all the double quotes (") in a textbox with single quotes ('). I used this code
text= Replace(text, """", "'"
This works fine (for normal double quotes).The problem comes in when you copy a double quote from MS Word and paste it in the text box. What happens is the double quote becomes slanted (“) so my code above can't filter it. I tried to do this
text= Replace(text, "““","'")
